Improvement in machines for pulverizing the soil



UNITED STATES GEORGE P. DE YO, OF GROTON TOWNSHIP, OHIO.

IMPROVEMENT IN MACHINES FOR PULVERIZING THE SOIL.

Specification forming part of Letters Patent No. 116,278, dated J une 27, 1871.

To all whom it may concern:

Be it known that I, GEORGE P. DE Yo, of Groton township, in the county of Erie and State of Ohio, have invented a certain new and Improved Machine for Pulverizing Soils; and I do hereby declare that the following is a full, clear, and complete description of the same, reference being had to the accompanying drawing making part of this specification, in which- Figure l is a side View of the machine. Fig. 2 is a plan View. Fig. 3 is a view of the under side.

Like letters of reference refer to like parts in the several views.

The nature of this invention relates to a pulverizing-machine and the object to be obtained thereby is the reduction of hard lumpy soils to a ne tilth by breaking up said, lumps by means of a series of grooved plates arranged in rows parallel with each other, land which are secured to the under side of a box-like frame or bateau in the manner as follows:

In the drawing, Fig. 2, A represents a strong` wooden frame or bateau, consisting of the sides B and a middle brace or piece, C, to which the bottom is secured. Said bottom consists of several pieces of plank, D, Fig. 1, fastened to the side pieces B in such way that the edge of the first piece 1 laps over onto the edge of the piece 2, next in order therewith, and the second laps onto the third, and so on, as shown in Fig. l, thereby making the bottom consist of several transverse narrow surfaces, having a slight angle in their relations with the horizontal line of the upper edge of the frame, as shown in the drawing. To ea-ch of the aforesaid transverse narrow surfaces is secured a plate or plates, E, Fig. l, having their outer surfaces formed into a series of angular grooves and ribs, as shown in Fig. 3. The relative position of the grooves and ribs of one plate to those of the adjacent plates is such that the ribs of one plate are in line with the grooves of the next in order, as shown in Fig. 3, the purpose of which will presently be shown.

The practical operationy of this machine is as follows: A team is geared to the machine at the point F. The operator takes his place on the seat G and drives off across the field. The

lulnps of dirt are run over by the machine, and,

by its weight and the angular character of the ribs of the plates, they are cut and crushed thereby into a tine condition, leaving the ground light and mellow.

By this machine the ground is not packed down and the lumps pressed into the ground, as is the case when a roller is used for crushing the lumps 5 but the lumps are cut a'nd broken up, and, by the sliding action of the grooves and ribs upon the broken lumps of dirt, they are reduced to a fine light tilth and less in long narrow ridges. This machine cannot clog up with dirt and stubble, as the grooves and ribs ofthe plates are kept4 clear of the sliding movements of the machine.

By arranging the plates so that the ribs and grooves alternate in their relation to each other, the work of reducing the lumps otl dirt is more effectually accomplished than if they were all arranged in a line with each other, as the unbroken lumps that may be left by one plate are met by the ribs of the others, so that what one plate fails to do the following ones will.

What I claim as my invention, and desire to secure by Letters Patent, is

The hereindescribed soil-pulverizing machine, consisting of the frame on bateau A provided with an overlapping bottom consisting of the pieces D, to which are secured the ribbed and grooved plates E, all arranged and combined in the manner substantially as described, and for the purpose specified.
